From 6173cc19c45d92ef0b7bc6aa008aa89bb29abbda Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sat, 27 Oct 2012 11:07:34 -0500 Subject: freedreno: gallium driver for adreno Currently works on a220. Others in the a2xx family look pretty similar and should be pretty straightforward to support with the same driver. The a3xx has a new shader ISA, and while many registers appear similar, the register addresses have been completely shuffled around. I am not sure yet whether it is best to support with the same driver, but different compiler, or whether it should be split into a different driver. v1: original v2: build file updates from review comments, and remove GPL licensed header files from msm kernel v3: smarter temp/pred register assignment, fix clear and depth/stencil format issues, resource_transfer fixes, scissor fixes Signed-off-by: Rob Clark --- src/gallium/drivers/freedreno/freedreno_resource.c | 248 +++++++++++++++++++++ 1 file changed, 248 insertions(+) create mode 100644 src/gallium/drivers/freedreno/freedreno_resource.c (limited to 'src/gallium/drivers/freedreno/freedreno_resource.c') diff --git a/src/gallium/drivers/freedreno/freedreno_resource.c b/src/gallium/drivers/freedreno/freedreno_resource.c new file mode 100644 index 00000000000..4458ba99557 --- /dev/null +++ b/src/gallium/drivers/freedreno/freedreno_resource.c @@ -0,0 +1,248 @@ +/* -*- mode: C; c-file-style: "k&r"; tab-width 4; indent-tabs-mode: t; -*- */ + +/* + * Copyright (C) 2012 Rob Clark + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
